The economic profit of Waterworks Irrigation is $115,000.
Economic profit is revenue less explicit cost and opportunity cost.
Explicit cost is the cost incurred in the course of running the start-up. It includes administrative cost, rent and cost of raw materials.
Opportunity cost or implicit cost is the cost of the next best option that a decision maker forgoes when he chooses one option over other options.
Economic profit = revenue - explicit cost - opportunity cost
$175,000 - $50,000 - $10,000 = $115,000
